STEI-RAZIN G-E'ZACHINE.

T all whom it-may concern:

Be it known that We, GHAnLEs Connwau. and DAVID J. FoL'rz. citizens oi the United States, residing at Salem, in the county of Columbiana and State of Ohio, have invented a certain new and useful Improvement in Spraying-Machines. of which the following is a full, clear. and exact description. reference being had. to the accompany ins drawings.

This invention relates to spraying devices of the portable tractor type and particu larly to that class of such devices adapted to be moved along a row or between rows of plants, the traction of a Wheel providing the necessarjf power for sprayin' .v

' An object of our invention is to provide a tractor spraying machine of such nature, which shall be Yery efficient in operation and strong and durable in construction.

- Another object; is to so construct the machine that it shall be simple and may he comparatively cheaply manufactured.

More specific objects are to provide for conveniently. converting the device into a hand operated spraying device, and still anvother object is to provide a simple means I for holding'the spraying: nozzles, which may be readily adjusted to allow for various sizes of plants and Width of rows.

Other objects Will become apparent in the following description and the essential characteristics are set forth in the claims.

,In the drawings: Figure lis' a perspective View of our machine. Fig. 2 is longitudinal' Vertical section of the same.

The frame of our machine comprises two tubular handlebars 10 each adapted to be secured at their forward ends to trunnion brackets 11, which have clamps 12 embracing the ends of the'handle bars and are held in place by suitable bolts. The brackets extend inwardly and then forwardly and are supported by means of a suitable axle 16 having its ends journaled therein and carriedby the Wheelie). .Toward the rear the handle bars diverse and are bent upwardly.

and then rearwardly, forming suitableham dies by Whlch the machme niay be moved.

When stationa y. the machine is carried,

on supports ls comprising U-shaped members adapted: to reston the ground. The rear'leg of each support extends. vertically,

to the underside of the handle bar and is bent rearwardly, iorrning a lip adapted to Specification of Letters Patent.

hlounted on for-r handle bars, are two subsi n'tiail frarncs 20 and 21. prefieic tegral castings. the upward and upper cross march-er oi Ai. legs arefornied hoi the handle hare and having portions the lips ends of the legs r 4 won o able screws i i bosses engage these 1 ets to the handle ha. the supports in hers connecting u ne-r of each of the i upper surface flanged ring ri end of a suhstan This ring is provided, with ing ears lying over the to members of the brackets 2 cured thereto by means off the holes of which are so s of the ears may lie on the either bracket.

On the top oi the "in cular cover formed of riding access to the container. member 28 which is secured to by means s1 3 a boss 30 which is her (lei-,3? of a suitable pump. Above the boss 3 with a usual pressr which the plunger K shown. At the lower one. bar is provided with a suitable adapted to rest on the bottom '2 a suitable pine-i=- upwardly entendix' bracing the ox handle comprises a strut 42 having a bifur-.

cated upper end pivoted to the handle lever by means of a bolt 41 and a bifurcated lower end embracing integral ears in the cover plate 28 to which it is pivoted by means of a removable pin or bolt.

The forward end of the handle lever is embraced between two parallel strips 46 of a yoke-shaped pitman 48. At their upper ends these strips are integrally connected as shown, and are pivoted at their lower ends to the outer ends or" crank arms 50 rigidly mounted on the ends of the axle of the wheel 15. The handle lever may be pivotally connected to the yoke pitman by means of a re movable pin 52, secured in place by a tapered plug 53 extending through a hole in this pin. This pin extends through holes 5% in the strips l6 of the yoke pitman and through a hole 55 in the handle lever. Thus it will be seen that when it is desired to use the pump as a tractor, the parts just described may be connected as shown in Fig. 1, then by moving the device along the grounchtlie rotation of the wheel 15 through the cranks 50 and pitman 48 will oscillate the handle lever 4C0 and operate the pump within the tank. In order to operate the pump by hand, the pin 52 may be removed, the yoke pitman allowed to rest against the upper end of the strut ll as shown in Fig 2, in which position it does not interfere with the free movement of the handle lever, or the yoke maybe entirely removed;

Extending from the lower portion of the chamber 33 of the pump, may beprovidedshort lengths of hose 00, connected to the ends of short pipes 61 having at their other ends suitable spraying nozzles 62. These pipes 61 may be mount-ed in clamp blocks 63 through which they are slidable, these clamp blocks having set screws til adapted to enpipes to hold them in any desired position. The clamping blocks thus are mounted on a projecting linger or stud 65, preferably integral with the frame bracket 20. The clamp blocks may be moved about this stud and clamped at any desired angle by means of set screws 67. Thus the nozzles may be placed in any desired position by gage the sliding the pipes through the clamps and changing their angles to provide for various sizes of plants and different widths of rows. 1f desired, the clamps may be mounted on a similar finger 65 on the forward frame bracket 21. i

The pivot block-36 has a laterally project ing arm 68 secured to the upper end of a rod 69 having at its lower end a suitable agitator 70 adapted to keep the mixture within the tank 26 stirred when the pump is in operation. The hinged coyer plate 29 may be provided with a suitable hook 752 which ma) chine and pumping by hand.

be turned to engage the rod 69 to hold the cover plate, when desired. Braces 74; may be provided extending from the trunnion brackets 11 to the frame bracket 21, to add rigidity to the frame.

From the foregoing description it will be seen that we have provided a tractor spraymg device which may be very conveniently operated, which is simple in construction and which has no parts liable to get out of order. the flanged ring may bedisconnected' from the frame brackets 20 and 21 by removing the bolts holdingthe same, and may be socured with the cars 27 reversed, bringing the pump and handle lever toward the rear where it may be more readily reached by an operator without leaving his position at the handles.

In using our machine, it is convenient to draw out the pin 52and re-insert it with the pitman free between the strut 41 and the pin.

In this condition the device is wheeled to the place of use, then the pitman is connected, thepipes 61 are adjusted, if necessary, to give the proper spread and direction to the spray, and the rolling forward of the device between the rows properlysprays them. When the handle is disconnected any occa- 'sional spraying may be conveniently done by the operator standing in front of the me- If hand spraying is desired for any considerable time the bolts 27 may be disconnected and the tank and pump turned around'diametrically to bring the pump handle into convenient position for the operator; or the pump handle may be disconnected at 37 and ll and turned in the opposite direction and the pins inserted with theend of the lever pivoted to the strut and the intermediate portion connected with the pump rod.

It will be noted that the forward ends of i the handle-bars are embraced by the clamps l2, and which may be loosened byloosening the bolts. Thus the rear ends of the handlebars may be turned inwardly or outwardly It will also be noted that if desired,

by loosening these clamps and the set screws which, support the frame, the handle-bars extending loosely through the frame members supporting the tank. This allows an adjustment of the distance between the hendles to bring them in the most desirable position for each individual operator.

Having thus described our invention, what We claim is': r i
